HOT-WATER RADIATOR HAVING MEANS THEREIN TO RELEASE THE RADIATOR OF THE AIR.

Patented J an. 3%), 191?.

Application filed December 15, 1915. Serial No. 67,034.

To all whom it may concern:

Be it known that I, JOSEPH ELenR, a citizen of the United States, residing at Chlcago, in the county of Cook and State of Illinois, have invented a Hot-Water Radiator Having Means Therein to Release the Radiator of the Air, of which the following is a specification.

My invention relates to automatic radiators for use in connection with hot water.

All radiators now in use for hot water have air vents. They are regulated by hand which requires lots of labor and is considered a nuisance. Automatic valves have been tried having float means within the shell of the valve. A float means incased within a shell cannot be operated properly for the reason that the water must pass into the valve and then operate the float. The compression force of the water is too indirect and the smallamount of water that enters the shell is forced all around the shell which causes normal pressure within the shell both at the top and bottom of the float within the shell. The weight of the float causes the float to bob up and down under pressure and the valve is unseated thereby. Weights have been used to counteract on the float. They merely act to balance the float and the result is the same.

All valves in use are attached to the outside of the radiator and are also disordered. by being tampered with. The object of my invention is to provide the radiator with an inner function that cannot be tampered with and cause the radiator to be a self acting operant that exhausts the air and allows the sections to become filledwith water.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view of a hot water radiator with a part broken away showing a means within the radiator. Fig. 2 shows united parts comprising a combination vent and float valve.

Like numerals refer to like parts throughout the several figures.

Reforrin g now to the accompanying drawings, I have shown a hot water radiator 1 having the valve 2 embodied in position for use.

The valve 2 is composed of parts, the body part 3 is connected to the connecting part 4; the connecting part 4 is attached to the lever connecting part 5. The lever connecting part 5 is connected to the valve stem part 6, the float 7 is also attached to the connecting lever part 5 as shown. Part 8 is a tapped threaded plug, having an opening 9. The valve 2 has a threaded end 10. The threaded end 10 is screwed into the threaded tapped opening 9 of the plug 8. The valve 2 is made to pass into the tapped opening 11 at the top of the radiator l and the threaded plug 8 is then screwed into the threaded opening 11 of the radiator 1. The plug 8 is marked so that when it is screwed up the valve 2 may be turned to its proper position as shown, which allows the air release pipe 12 to be at the top. The air release pipe 12 communicates with the atmosphere through the opening 13, shown at the top of the radiator 1. All plugs have means to admit of their being screwed up. An ordinary plug is used for the purpose shown.

The operation is as follows: The water rises in the radiator and exhausts the air out through the opening 13 into the atmosphere. When the water rises to the float 7 it lifts the float and seats the valve and the radiator is released of the air and filled with water, thereby becoming a self acting operant.

I have shown in the drawings a simple and particular construction for purposes of illustration, but it is of course evident that this construction may be varied in many particulars without departing from the spirit of the invention.

I claim:

An air vent Valve for radiators adapted to be inserted into a radiator unit through one of the screw threaded standard upper joint openings of the unit, and screw threaded means cooperating with the opening and the valve to maintain the valve in operative position in the radiator.

In testimony whereof, I aflix my signature in the presence of two Witnesses.

JOSEPH ELGER.
